Urban sensors are often used to monitor illegal activity — from identifying drivers that run red lights to generating predictive crime maps — but they can also collect data for quality-of-life improvements like reducing emissions and preventing car accidents.
The big picture: Municipalities could use anonymized, secure sensor data in combination with advanced computing to better understand how people travel through and use public space, without sacrificing individual privacy.
What’s happening: Academic researchers and urban planners can leverage the latest sensors — including “camera-as-sensor” technologies, which convert a camera’s optical image into an electronic signal — to gather and share insights about roads, intersections and public spaces.
- Yes, but: Ensuring the data collected is protected and anonymized will be crucial to earning public trust in these efforts.
Details: These projects rely on a combination of video streams, computer vision, AI, and edge computing (computing done near the data source, not in the cloud).
- Metro21: Smart Cities Institute at Carnegie Mellon University collaborated with Urban Data Eye and the Pittsburgh Downtown Partnership to identify pedestrian movement patterns based on CCTV footage and live-streaming. The project found that furniture and tree placement impact where pedestrians congregate, which could inform planning or redesign decisions.
- Platform Pittsburgh, another Metro21 project, analyzed urban video streams to identify frequent sites of near-miss accidents, which could guide the creation of safer intersections. It is also tracking emissions based on images of truck's tailpipes.
- Numina has partnered with city planners, mobility companies, and other stakeholders in Jacksonville, Las Vegas and St. Louis to collect and analyze data on the walkability and bike-ability of urban areas using light-post-mounted sensors and computer vision.
This technology has applications outside urban areas, as well. Project Diversita developed a camera and computing system that can identify over 5,000 different animal species to inform wildlife research and management.
The bottom line: Applying machine learning and edge computing to sensor and camera data could inform future urban planning initiatives, the allocation of public space, and even conservation efforts.
